Zusammenfassung: | The invention relates to a hydraulic control valve. A new means of achieving a valve float position in a closed centered hydraulic control valve. The valve has a main spool position whereby pressure compensator load sense control pressure is drained to tank through the main spool. Secondly, a pin acts on the pressure compensator to prevent the main pump flow from reaching the main section spool. Finally, the new spool position adds a connection from the consumer to tank, enabling a float position.
本发明涉及液压控制阀。一种在闭式中心液压控制阀中实现阀浮动位置的新方法。阀具有主阀芯位置,由此压力补偿器负载感测控制压力通过主阀芯连通到箱。其次,销作用在压力补偿器上,以阻止主泵流到达主区段阀芯。最后,新的阀芯位置附加从消耗装置到箱的连接,从而实现浮动位置。 |
